test the hand sanitizers on bacterial colonies that are kept in the exact same environmental conditions, such as temperature and light level
Answer: Option D.
Less; at the earliest possible stage.
Explanation:
Protein synthesis refers to the process in which living cells can produce proteins
This occur in two stages;
Transcription and translation.
Transcription refers to transfer of DNA genetic instructional to MRNA in the nucleus of cells.
Translation, after DNA has been transcribed to MRNA, it is then translated to DNA.
When cells intervene in protein synthesis, less energy is used and the cells will regulate the protein synthesis at the earliest possible stage.
Answer:
Stabilize the DNA
Explanation:
DNA is defined as deoxyribonucleic acid comprises of phosphates group, deoxyribose sugar , amino acids base pairs namely adenine, cytosine , ,guanine and thymine.
Increase in temperature denatures the amino acids and proteins which means losing the basic structural unique properties .When it is denatured there is going to be a big difficulty in the use .
The results gotten from the DNA isolation if it isn't kept in an ice bath will be very inaccurate which is one of the main reasons why the DNA has to be put in it for the best result.
Answer:
D: Both B and C
Explanation:
The process is never linear, scientists often answer a question that then leads to another one, therefore B is correct. C is also correct because hypotheses often change after an experiment has been done, and the goal of science is to constantly find more accurate information.
Answer:
B. 0.50
Explanation:
The estimated frequency of allele A in the gene pool is 0.50. Allele A is a variant form of gene which has different forms located at same position. Allele frequency determines common presence of genetic locus of an allele in the population. It is calculated by dividing the number of common allele that appears in the population by total number of copies of genes.
